Marvell's quad-core chip, Armada XP, announced on Monday with ARM architecture, making ARM a direct competitor for Intel and AMD in the server chip market.
ARM licenses processor designs to chip vendors such as Marvell, Texas Instruments, Samsung and Qualcomm. Most smart phones use ARM architecture chips and ARM is entering the tablet and server chip markets. Since 2008, ARM has repeatedly stated that it wants to enter the server market. Marvell was one of the first companies to announce ARM-based server chips.
Nathan Brookwood, chief analyst at market research firm Insight 64, said that compared to Intel's and AMD's chips, the performance of low-power ARM architecture chips is higher. ARM-based servers can occupy a place in low-end servers that do not require high computing performance. For example, this type of server is well-suited to handle web transactions. Many web servers run the Linux operating system and ARM architecture chips support Linux.
Brookwood said, "Intel is trying to launch tablets and smart phone chips to enter the territories of ARM; ARM is trying to enter Intel's territory through the launch of low-end server chips. In the next 2-4 years, the competition between Intel and ARM will be very interesting."
As companies consider cutting energy consumption, servers equipped with low-power chips are gaining attention. For example, SeaMicro's recently introduced low-power SM10000 server integrates 512 Intel Atom chips. AMD also said that the company is considering launching low-power server chips.
Dean McCarron, chief analyst at market research firm Mercury Research, said that although data centers increasingly deploy low-power servers, companies may not plan to change their existing infrastructure. The enterprise's business has a high degree of trust in the IT infrastructure. Unless it is considered that the new architecture is very reliable, the server architecture will not be easily replaced. In addition to reliability, ARM also needs a lot of application support.
In September, ARM announced a Cortex-A15 design that is suitable for server tasks. It supports virtual technology, the highest ITB physical memory, and can increase performance by adding kernels. However, no company has yet announced a chip using the Cortex-A15 design.
Brookwood said that the current ARM architecture chip design will affect its popularity in the server market. For example, only supporting 4GB of physical memory can affect the operation of the server software. The current design and the Cortex-A15 both use 32-bit technology, and Intel and AMD's server chips have turned to 64-bit technology years ago, and ARM is lagging behind competitors in this regard. Brookwood said that the next-generation ARM chip design announced in 2011 or 2012 will support 64-bit technology.
